YET US Inc.'s XtraDrive servo system features patented NCT control technology. The unique adaptive control structure is said to eliminate difficult and time-consuming system re-tuning by automatically accommodating changing load requirements. The non-linear technology achieves zero settling time, optimizing non-linear gain control and overall system productivity. The complete servo system includes an integrated amplifier with embedded 1.5 axis controller.

A stacking, laminating and coating service for small motors, stators and gyroscopes that permits smoother, more densely populated wire-winding is being offered by Applied Plastics Co., Inc. The service holds lamination alignment to within √Ç¬±0.0005 in. and includes deburring and selective coating from 0.002 to 0.005 in. thick in one pass, to meet MIL specs. Permitting smoother and tighter wire-winding for motors, stators, and gyroscopes, the service is said to help prevent wire cuts and shorts, resulting in less scrap.

AllMotion Inc. has announced the dual axis EZHR17EN stepper motor controller and driver system. Units are 40 x 40 mm with encoder feedback that provides up to 2 A drive current for one axis and up to 1 A for the second with optional second stepper or bidirectional dc driver daughtercard. The EZHR17EN and daughtercard can microstep up to 1/256 and 1/16 steps, respectively.

Sanyo DC Micro Motor Division has developed a micro motor featuring a ceramic air bearing design. The PM series brushless motor design uses air as a lubricant with the sleeve and shaft of the ceramic air bearings containing a 3- to 5-micron gap between them.

The Bug series of linear actuators from Ultra Motion has been redesigned to offer improved strength, precision and reliability; while keeping the same footprint. New features of the series include ABEC-7 angular contact bearings and interchangeable motor mounting plates. A Kevlar drive belt and pulleys provides 1:1, 2:1, 3:1, 4:1 and 5:1 drive ratios with low backlash and low audible noise by eliminating gears between the motor and the drive screw.

Users of Allen-Bradley PowerFlex AC drives and legacy SCANport-enabled Allen-Bradley drives can now wirelessly program, troubleshoot and monitor their drives using a hand-held PC with Pocket DriveExplorer software from Rockwell Automation. Throughout a facility, it is said users can freely program and troubleshoot drives using a Wireless Interface Module (WIM) linked to a Pocket PC.

A Kevlar drive belt and pulleys provides 1:1, 2:1, 3:1, 4:1 and 5:1 drive ratios with low backlash and low audible noise by eliminating gears between the motor and the drive screw. There are 17 motor options including: dc, dc servo, dc gearmotors, steppers, and Animatic "Smart Motors." Absolute position feedback is available so that position is remembered even if power is lost.

Tol-O-Matic has introduced the B3W series electric belt drive actuator. In most applications the B3W can be used as a direct drop-in replacement for the company's B3B actuator, and is said to allow users to accelerate larger loads faster, without additional cost. The B3W is designed for high wear resistance, repeatable accuracy and high load capacities.

Uhing Company has announced an option for its model RG rolling ring linear drive assemblies whereby the end stop assemblies are fitted with machined V-shaped cams to decrease the linear speed of the drive prior to reversal without using electronic controls or reducing motor speed.
After reversal, the cams are said to permit smooth ramp up of the drive
speed eliminating possible whipping action of tools such as spray heads
or cutting blades.
